This notice is to inform Large Spark-Ignition (LSI) equipment
operators of the Air Resources Board’s (ARB) intent to commence
enforcement of all requirements of the In Use Off Road Large
Spark-Ignition (LSI) Engine Fleet Regulation (LSI Fleet
Regulation or Regulation). The regulation was filed with the
California Secretary of State in May 2007, at which time the
requirements of the LSI Fleet Regulation came into effect and
were fully enforceable except for those parts of the Regulation
that required United States Environmental Protection Agency (U.S.
EPA) authorization under the federal Clean Air Act. U.S. EPA
granted California authorization on April 4, 2012. With the
issuance of this authorization, those provisions are now
enforceable as well. ARB anticipates that it will commence the
enforcement process slowly, initially auditing a small number of
facilities for training purposes. Full scale enforcement will
commence following the completion of training near the end of
this year.

Background
On May 25, 2006, ARB adopted the In-Use Off-Road Large
Spark-Ignition Engine Fleet Regulation (LSI Fleet Regulation or
Regulation). The LSI Fleet Regulation establishes fleet average
emission level standards for operators of in-use fleets of
forklifts, industrial tow tractors, industrial sweeper/scrubbers,
and pieces of airport ground support equipment (GSE) powered by
LSI engines. The Regulation also establishes recordkeeping
requirements. Under section 209(e)(2) of the federal Clean Air
Act, California may enforce its own emission standards and other
requirements related to the control of emissions from off-road
engines and equipment not conclusively preempted by section
209(e)(1) – new locomotives and engines and new off-road engines
less than 175 horsepower used in farm and construction equipment
and vehicles – so long as it first applies for and receives
authorization from the Administrator of U.S. EPA. (77 Fed. Ref.
20388, April 4, 2012.)

Fleet Regulation, please call the LSI Fleet Regulation
